The 67-year-old Newton resident is a former head of the Democratic National Committee. He was elected state treasurer in 2010, his first elective office.

State Sen. Dan Wolf, of Harwich, announced his candidacy for governor on Wednesday in a statement and a video posted on his campaign website.

"For the working people of Massachusetts, and our children, the future is uncertain. Despite progress, we still have an economy that is not working for many of us," Wolf said in the video.

"We need an economy not guided by special interests whose short-term goals are holding us back from fulfilling our promise," he said.

The two-term state senator and businessman helped create Cape Air.

Donald Berwick, a pediatrician from Newton and former top health care official in President Barack Obama's administration, and Joseph Avellone, a life sciences company executive and former Wellesley selectmen, previously announced their candidacies for the Democratic nomination for governor.

On the Republican side, the list of potential candidates includes 2010 Republican gubernatorial nominee and former Harvard Pilgrim Health Care CEO Charles Baker and former U.S. Sen. Scott Brown.
